The most expensive GLE 580 is the only non-AMG GLE with a V8 - a 4.0-liter with 483 hp and 516 lb-ft, also with EQ Boost. Its 362 hp and 369 lb-ft are delivered in a creamy smooth fashion and it's much more refined than the four-pot. The GLE 450 is a significant step up with a 3.0-liter gas engine supplemented by a 21-hp/184-lb-ft EQ Boost hybrid-assistance system. Performance is adequate and the engine is acceptably refined if not extended. This model is available in RWD or 4Matic AWD. The base 2.0-liter gas engine in the GLE 350 does without hybrid assistance and produces 255 hp and 273 lb-ft of torque, which is transmitted to the road via a nine-speed torque-converter automatic transmission common to all GLE models. Towing capacities for the GLE vary from 5,950 pounds for the RWD GLE 350 up to 7,700 lbs for the 450 4Matic.

The heavier Audi Q7 is slowest at 5.7 seconds.

The 3.0-liter turbocharged engines of the GLE's key competitors both develop less power, but it matters little as the lighter BMW X5 hits 60 mph in 5.3 seconds and the more powerful version drops into the low fours. The GLE 580's twin-turbo 4.0-liter V8 with EQ Boost develops 483 hp and 516 lb-ft of torque, good enough for a 4.9-second sprint time and a higher top speed of 155 mph. Both the GLE 350 and 450 models are limited to 130 mph. The GLE 450 4Matic's 3.0-liter inline-six with EQ Boost mild-hybrid assistance offers 362 hp and completes the 0-60 sprint in 5.5 seconds. The entry-level GLE 350's turbocharged 2.0L four-cylinder engine develops 255 horsepower and can complete the 0-60-mph sprint in seven seconds in RWD guise and 7.1 seconds with AWD. The GLE is offered with three engine choices, all paired with a nine-speed automatic transmission.
